Eh, the longest place name in the world is "Krung Thep Mahanakhon Amon Rattanakosin Mahinthara Yuthaya Mahadilok Phop Noppharat Ratchathani Burirom Udomratchaniwet Mahasathan Amon Phiman Awatan Sathit Sakkathattiya Witsanukam Prasit"and that is the full official name of Thailand's Capital Krung Thep (Bangkok)

When I was 11, I stayed with family friends on [Webster Lake] and was required to learn how to say the lake name, which, sounded-out is: "Lake Sha-gog-a-gog Man-sha-gog-a-gog Shu-bun-a-gung-a-mog." That summer was one of the best :)
